O.K.-Question on fuel tank set up for aerobatic planes such as G-202, Extra,etc. Has anyone experimented with longer clunk lines so that the clunk will travel to all four corners of the tank? Longer meaning approx. five inches in length to allow the cluck to freely travel in the tank. I am currently flying a Great Planes G-202 with a Saito .91, I have a good tune up on the engine, yet every once in a while during a long verticle drop, the engine will flame out. This only happens during verticle drops. This set up will idle at 1950-2100rpm for more than three minutes then throttle up with no issues.
